Dear aspirant,

HCl can be generated by the reaction of sulfuric acid with sodium chloride:

NaCl + H2SO4 → NaHSO4 + HCl

procedure:

We can produce Hydrogen Chloride in the laboratory by treating sodium chloride with concentrated sulphuric acid. then, heat this mixture up to 420K.

This reaction occurs at room temperature.

Hope this helps you out!

All the best
